실험 절차

In a similar manner to Step 2 of Example 2, 3-amino-4-iodo-6-bromophthalimide (100 mg, 0.273 mmol) was dissolved in THF (7 mL), and the solution was treated with 4-hydroxymethylphenylboronic acid (83 mg, 0.55 mmol), tetrakis(triphenylphosphine)palladium (25 mg, 0.022 mmol) and copper(I)thiophene-2-carboxylate (104 mg, 0.546 mmol), followed by purification by preparative thin-layer chromatography (chloroform/methanol=15/1) to obtain 3-amino-4-(hydroxymethylphenyl)-6-bromophthalimide (61 mg, yield 64%) and 3-amino-4,6-di(4-hydroxymethylphenyl)phthalimide (29 mg, yield 29%).
